Plop comic books are best described as a horror / humor anthology. Issues were hosted by three ghoulish characters with biblical names: Cain, Abel, and Eve. An issue would typically contain a story told by each of the characters, each bidding to outdo the others in fiendishness. An illustrative tale involved a gourmet whose love for frogs' legs leads to a predictable amphibian revenge: he is left without lower limbs and is doomed to negotiate the world on a trolley.
Basil Wolverton and Wallace Wood provided distinctive covers for the first 19 issues, each depicting a freakish character of some kind. Sergio Aragones, better known for his work in MAD, drew many of the more cartoonish tales and most of the surrounding banter between the three hosts.
